我目前有一个问题，我的旋转木马。我的意思是它的工作正常，但有wierd符号新的按钮，以改变幻灯片。

我不知道如何解决这个问题。下面是它的代码。

<div class="well">

<div id="myCarousel" class="carousel slide">

<ol class="carousel-indicators">
    <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
    <li data-target="#myCarousel" data-slide-to="1"></li>
    <li data-target="#myCarousel" data-slide-to="2"></li>
</ol>

<!-- Carousel items -->
<div class="carousel-inner">

<div class="item active">
    <div class="row-fluid">
      <div class="span3"><a href="#x" class="thumbnail"><img src="http://placehold.it/250x250" alt="Image" style="max-width:100%;" /></a></div>

<!-- This is just a little bit of custom CSS code to enhance things. Feel free to place this in your main CSS file. I've commented to say what each bit does. --> 
<style type="text/css">
/* Removes the default 20px margin and creates some padding space for the indicators and controls */
.carousel {
    margin-bottom: 0;
    padding: 0 40px 30px 40px;

/* Reposition the controls slightly */

<!-- Call jQuery 1.9, call bootstrap.js and run the carousel when the DOM is ready. Slide every 10 seconds. -->

$(document).ready(function() {

    })
});
</script>
